Abstract design, development, structure and internal parts of the structure to be effective and safe. To reduce the risk of accidents caused by the actions or the insert. Which has resulted in injury and loss of life of the vehicle. So it was a trial for the parts that are able to minimize the damage from any inserts or the bump of a structure called the "energy absorbing" into the structure in order to absorb energy absorbing energy. by collisions or action insertion and reduce structural damage, primarily to reduce the cost in lives and resources into product series of accidents caused by collision or action insert. The variables that affect the ability to absorb the energy of an energy absorbing material such as shape, size, thickness and behavioral damage. Etc. to carry gold is aimed at determining the energy absorption of the pipe walls, a tubular aluminum filler foam give Polyurethane under Torque (Torsion) using simulation in Abacus. and compared to the actual experimental work. The cross-sectional shape of the pipe at the trial, including the rectangular shape probe. Hexagonal cross-sectional shape The octagonal shape probe And a circular cross-sectional shape The density of the foam test is 50kg / m¬3,75kg / m3,100kg / m3. The analysis found that under torque. The circular pipe cross-sectional shape to absorb energy, the highest status a pipe shape of an octagon. Hexagonal cross-sectional shape The rectangular tubular shape and each has the power to absorb a minimum. The analysis of the density of the foam used to fill the pipeline. 50kg / m-3,75kg / m3,100kg / m3. The density of the foam pipe, aluminum is the optimum energy absorption is 100kg / m3 and a high density foam will absorb higher energy costs.
